Description

Function

1

BST

High side power transistor gate drive boost input

2

VIN

Power input, the input capacitor should be placed as close to VIN and

GND pin as possible

3

SW

Power switching node to connect inductor

4

GND

Ground

5

FB

Feedback input with reference voltage set to 0.923

6

COMP

Compensation node. A serial RC connected to this pin is required to

maintain the Buck converter control loop stable

7

EN

Enable input. Setting it to high level or connecting to Vin via a resistor

may turn on the chip, while setting it to ground level will turn off the chip

8

SS

Soft-start node. Connecting a 0.1uF capacitor to ground make the Buck

converter output rise smoothly
